Hi all and thanks in advance to whoever is going to be kind enough to help me.
I'm currently training a network and surprisingly my problem is that it's underfitting and I can't manage to make behave any differently.
I'm trying to build a regressor, with a 2-dim real label.
here is the architecture file:
name: "FKPReg"
layers {
name: "fkp"
top: "data"
top: "label"
type: HDF5_DATA
hdf5_data_param {
source: "train.txt"
batch_size: 2000
shuffle: true
}
include: { phase: TRAIN }
}
layers {
name: "data"
type: HDF5_DATA
top: "data"
top: "label"
hdf5_data_param {
source: "test.txt"
batch_size: 100
}
include: { phase: TEST }
}
layers {
name: "ip1"
type: INNER_PRODUCT
bottom: "data"
top: "ip1"
inner_product_param {
num_output: 314
bias_filler {
type: "constant"
value: 0.1
}
}
}
layers {
name: "relu4"
type: RELU
bottom: "ip1"
top: "ip1"
}
layers {
name: "ip3"
type: INNER_PRODUCT
bottom: "ip1"
top: "ip3"
inner_product_param {
num_output: 2
bias_filler {
type: "constant"
value: 0.1
}
}
}
layers {
name: "loss"
type: EUCLIDEAN_LOSS
bottom: "ip3"
bottom: "label"
top: "loss"
}
This is the parameter file:
net: "no_conv_2000.prototxt"
test_iter: 6
test_interval: 1000
base_lr: 0.1
lr_policy: "step"
gamma: 0.1
weight_decay: 0
stepsize: 10000
display: 100
max_iter: 200000
momentum: 0
snapshot: 1000
snapshot_prefix: "experiments/single_hidden_2000"
solver_mode: CPU
I've tried to increase the number of hidden units but it doesn't seem to help that much..
Thanks again!!
